SPECIFICATION forming part of Letters Patent No. 585,889, dated July 6,1897. Application filed May 16, 1896. Serial No. 591,846. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT A. PAGE, a citizen of the United States, anda resident of the town of East Haven, county of New Haven, in the Stateof Connecticut, have invented a new and useful Improvement in Planes,fully set forth and described in the following specification, taken inconnection with the accompanying drawings, which form a part thereof,and in which Figure 1 represents a side elevation of a plane embodyingmy invention; Fig. 2, a top view of the same; Fig. 3, a verticallongitudinal section on the line 3 3 of Fig. 2; Fig. 4, a top view ofthe frame; Fig. 5, a bottom view of the plane iron or bit; Fig. 6, acorresponding View of the clamping-cap; Fig. 7, a detail of theclamping-lever.

In all the figures similar letters of reference represent like parts.

This invention relates to hand-planes and it consists in a novelconstruction of parts, which when assembled produce a simple deviceeasily regulated or adjusted.

The invention refers more particularly to an improved method of lockingthe plane iron orbit between the frog and the clamping-cap by means of alever pivoted in said clam pingcap to swing vertically beyond itsdead-center, as set forth and described, together with otherimprovements, hereinafter.

Referring to the drawings for the more particular description, Arepresents the stock or frame, and a the throat thereof.

B is the plane iron or bit, with 1) its cutting edge, the bit having alongitudinal slot 1), extending central therein, and on the under sideadjacent to said slot Z7 and extending lengthwise therefrom a series ofteeth 6 Mounted on the frame A is a frog 0, which consists of twoparallel vertical plates with diagonal upper edges, the plates beingunited by a block 0, slotted vertically a short distance downward fromits top. I11 the slot of the block 0 is pivoted by means of the pin 01an adjusting-lever D, having on its upper side a number of teeth d,which extend slightly above the level of the frog C. The free end ofsaid lever has a horizontal slot d of sufficient width to receive theedge of the adjustingnut E, threaded to run on the vertical screw F,rigidly mounted near the end of the frame A. The edge of this nut Ebeing knurled, it may be easily screwed up and down, and with themovement of the nut the engagement of the slot d of the lever D raisesand lowers the free end thereof, which swings the teeth d forward orback. As the bit B is adapted to rest on the frog 0, the teeth (1 of theadjusting-lever D engage with the teeth 12 on the under side of the bit,and the movement of the teeth produced by the adj Listing-nut E on screwF is communicated to the bit, the edge of which is then forced deeperinto or withdrawn from the throat aof the frame A.

Pivoted by a screw 9 to the under side of the bit B adjacent to theteeth 19 is a forked lever Gr, the fork g of the lever lying across theteeth 11 and the other end projecting beyond the end of the bit. Thislever G is capable of swinging in a horizontal plane, and when the bitis fitted on the frog 0 the fork g is adapted to embrace the teeth (1 onthe adj usting-lever D. When the fork g is thus engaged with the teethcl, which are secure against any transverse movement, the swinging ofthe lever G will tend to force the upper end of the bit to one side orthe other, and as the bit is practically pivoted by the screw I,described hereinafter, the swinging will give a side adjustment orequalizing movement to square the cutting edge Z).

Between the throat a and the frog C on the frame A is mounted thecylindrical block I-I, centrally bored and having a diagonal upper endcorresponding to the edge of the frog 0. The central bore is internallythreaded for a screw I, over which the slot 1) of the bit is adapted tofit.

A clamping-cap L, the rear end of which is rounded, as shown, Figs. 1and 3, has in its forward part a slot Z, corresponding to the diameterof the head of the screw I and extending rearwardly from the slot Z, asecondary slot Z corresponding to the diameter of the shank of the screwI. A rectangular slot Z extends centrally in the cap L, and on eitherside near its rear end are depending ears M. Pivoted between the ears M,by the pin m at its elbow, is ,a substantially rightangled lever N. Onearm nof this lever is rounded to bear on the upper side of the bit B, ashereinafter described, and the other arm n is formed to correspond Withthe upper side of the clamping-cap L, as shown in Figs. 1, 3, and 7, theextreme end being flattened and widened to act as a thumb-piece,

When the clamping-cap is placed over the bit B, the slot Z being fittedover the screw I and the cap forced forward so that the screw is engagedin the slot Z, the right-angled lever H is used as a clamp to hold theparts together and rigidly secure them in place.

Upon the forward movement of the arm n the other arm n bites against thebit B, and the tendency is to force the clamping-cap L groward intocloser engagement with screw 1,

The slight elasticity in the cast metal allows the clamping-cap to beraised as the arm n of the clamp passes the perpendicular, so that whenin the position shown in Fig. 1 the parts are securely locked. The screwI may be raised or lowered to secure the right adjustment of theclamping-cap and clamp. The forward position of the clamp when the partsof the plane are locked and its conformity with the surface of theclamping-cap makes a smooth handle and prevents the hand of the operatorfrom being caught on the clamp when the plane is in use.

A finger-knob P is shown in the forward I part of the frame beyond thethroat, which may also serve as an adjusting-screw for a slidingthroat-piece, as is often the case.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is

In a plane, the combination with the frame; of the bit; a support on theframe for the bit; a locking device mounted on the frame; a clamping-capabove the bit, forming the main handle portion of the plane, and havingits forward end adapted to engage with said locking device to lock theforward end of the bit, while its rear end is provided with alongitudinal slot; a substantially right-angled clamp pivoted in saidclamping-cap, with one arm adapted to swing forward in said longitudinalslot, and the other arm to bear on the bit and lock the rear of thesame, when the forwardly swinging arm has assumed a position inalinernent with the main portion of said clamping-cap; and means on saidclamp for disengaging it from its locked position, substantially asdescribed.

In witness whereof I have hereunto set my hand at New Haven, in thecounty of New Haven, State of Connecticut, this 11th day of May, 1896.
